From the second I put brush to soap to the just after I've cleaned up and put aftershave on, it takes me 25-30 minutes. I almost wish it took longer. It's the most enjoyable and relaxing time of my day, the part I most look forward to. I definitely don't rush it!

FWIW, when I first started traditional wetshaving with a DE, it was taking me roughly 45-50 minutes. As I set into my routine and got better and more efficient at making lather, cleaning up, knowing the grain of my face and the passes I needed, etc, etc, it came down to about 25 minutes even with the DE. The straight doesn't take me much longer, save for stropping, which is a minute or less.
